Track motion and lots of keyframes. You should also zoom in a tad so the edge of the frame doesn't go off the screen, that tends to give the game away.

Same thing that does track motion. Suggest you check out the manual or even the on line help will fill you in.
As yor're new perhaps the best bit of advice I can give you is, don't be afraid to experiment, nothing actually happens to your source material, keep saving projects with different names as you play around. Don't get focussed on specific tasks, try lots of things just to see what they do, you'll remember them later on. Also download lots of sample projects to see how things are done. By itself Vegas doesn't have that many built in tricks but you can build just about anything you need by from the building blocks that Vegas provides.
